Specification of Letters Patent.

Patented July 14, 1914.

Application filed June 11, 1913. Serial No. 772,984.

To all whom 'it-may concern.' y Y Be it known that I, CHARLES CHESTER EATON, a citizen of the United States, and resident of Brockton, county of Plymouth, lState of Massachusetts, have invented an Improvement in Processes of Making Shoes, of which the following description, in connection with the accompanying drawings, is

and the heel end of the outer sole has fre-` quently been split, out, or recessed so that it could be properly sprung around a heel lift, and the heel portion of the sole so sprung was nailed to the shoe in theusual manner.

My invention contemplates the production of a spring heel type of shoe, employing both an insole and an outer sole. I 4also prefer to make .such a shoe with a cushion heel, and protect they cushion so that it will be free from wear and willnevertheless act as the heel lift to give eXtra height to the 'heel around whichthe outer sole is to be' spr'ung to constitute the heel of` the shoe. As herein shown in a preferred form, I have illustrated the process yof making my improved shoe as an athletic type of shoe, although my process is equally applicable I toshoes of anystyle or type employing a spring heel. In carrying out my novelv process I first prepare an inner sole with a welt channel, extending said channel entirely around the. heel portion of the inner sole, as well as around the forepart.y I then assemble the upper and inner sole on a last in the usual manner and stitch thereto a welt by the usual welt inseem stitching machine, stitching the welt entirely around the heel, so that the assembled shoe thus prepared is supplied with a welt stitched entirely around the marginal portion of the upper, as welly as tothe insole. `,Preferably I start and l end the welt on the arch side of the shoe f at the heel breast, z'. e. at the left on a right, and at the' right on a left, shoe. I then prepare the-outer sole by rstmolding the same tof-substantially the shape at the heel breast which it is to occupy in the completed shoe. During this molding operatlon I also provide the outer surface of the outsole with corrugations or the like anti-slipping devices, particularly when the sole is to be applied to an athletic'shoe. This molding of the outer sole also conden'ses and compacts the leather thereof, laddingl considerably to the wearing qualities and forming the corrugations in the outer surface still further increases lthis condensing or compacting of the fibers of the leather. I prefer to so mold the outer sole that the heel breast will be at an' angle slanting inwardly and forwardlyto the -arch of the shoe, in'order to afford an arch'supporting or orthopedic effeet under the arch. I furtherso mold the outer sole as to form the heel breast of greater-'depth' at the forwardly` extended portion of the spring heelv to addv to the thickness ofthe support for the arch, thus securing a further' orthopedic feature, all beingwithin the purview ofmy patent. To the sole thus molded I apply at the heel portion' a cushion heel lift adapted to exactly register with the extent to which said heel has been molded, both with regard to the angle of the heel breast and theincrcasing depth at one side vrelatively with the depth at the other side, so that said heel lift will- In the drawings, illustrating an athletic.

orthopedic shoe made by my improved process, Figure 1 is a side view ofv such a shoe; Fi 2 is a view of the outer sole after it is mo ded, and with the cushion heel lift applied thereto; Fig. 3 is a View of the bottom of the sole after it is molded and corrugated; and Fig. 4 is a View in cross section on the line 4-4 of Fig. 3.

The shoe upper is indicated at l, a usual type of Oxford or low shoe being shown, the upper l being united to achannel insole 2 and a. welt 3 by inseam stitching 4, as illusf trated in Fig. 4: It will be understood that the welt groove or channel in the insole 2 is cut entirely around the heel in -order to allow for the stitching of the welt 3 entirely around the heel also, a stitched heel seat beingh thus provided in contra-distinction to the usual nail/ed heel seat. A suitable filling 5 may be applied to both forepart and heel part of the shoe# and theoutsole 6, to-

is completed by my process withouta nail;

or tack being left in it.l The cushion heel lift 7 may be 'of any suitable thickness desired, and while preferably of rubber or rubber-composition, may be ofother yielding and resilient material. The outsole stitching 8 which secures the cushion heel 7 to the shoe permits the cushion to yield and be flexed without any restraint and without affecting the holding of the stitches. In the shoe herein illustrated it'will be seen that theI heel breast 9 is preferably formed at anangle having the forwardly extended and thicker portion at the arch side 10 of the.

shoe thus causing the insole of ashoe to fit up snugly under the archl of the foot, and

provide an arch supporting, as well as orthopedic, construction. Preferably I make the shoe 'of the type herein shown without 'a shank stiffener vor the like rigid means, although such a stili'ener could bel employed if desired. My vimproved process, therefore, enables a cushion 'heel shoe to be made of the spring heel type, suitable for adult wear,

r and furthermore provides an extremely flexible shoe .and without a nail or tack in itsv Aentire construction. Furthermore, by molding the outer sole, as explained, I secure the advantages of the full limit of thickness and Wea-ring capability of the outer sole,

both at the heel breast 9 and throughoutthe entire` extent of the heel. This is of great importance, as heretofore 'it has been customary to'cut the vheelgportion of a springy heel shoe at 'the heel breast and to decrease the wearing thickness ofthe sole at this point. around the heel, theshoe can be readily repaired and the cushion heel lift 7 can be replaced, should it wear out before the' outer sole. By having the cushion lift, however, thus protected between the outsole andtthe By employing a welt construction heel .of Athe shoe, its wearing capacity is greatly lengthened and the full capacity of its yield or resilience is left unimpaired.

Having described my invention, 'what I claim as new and desire to secure by Letters Patent is: f

1. The process of making an orthopedic, spring heel shoe, which comprises molding t e outsole with the heel portion thereof Aoffset below the level of the adjacent end of.

the shank portion to form a recess for a lieel lift, and with the portion of the sole connecting said shank portion with said heel portion extending from the outside of the shank forwardly across the sole to the inside of `the shank to form an inclined heel breast f gradually increasingfdepth from said outer sidev ofthe shank tosaid inner side'thereof, securing a heel lift in said ref cess of such dimensionsI that the upper surface of said lift is substantially flush with the upper surface of said shank along their contacting edges, and finally securing the sole and heel lift to a shoe. v 42. The improved process of making a shoe having a leather outsole, comprising molding the tread surface of the outsole in substantially its final form,'simultaneously condensing portions of the outsole by a plurality of intersecting indentations," thereby formin spaced flat tread surfaces between said in entations to constitute antislipping devices, then applying the sole so preparedv to the bottom of a shoe having an upper, in-

sole and weltv extending entirely around the shoe bottom, and stitching the marginal portion of the sole and welt together.

3. The improved process of making a shoe having a leather outsole, comprising molding the'tread surface of the outsole in suby stantially its final form with the heel portion ofthe sole offset to constitute the tread face of the heel, simultaneously condensing both forepart and heel portions of the outsole bya plurality of intersecting indentations'thereby forming spaced flat tread surfaces`between said indentations to consti-A tute, antislipping devices, then applying the sole 'so prepared to the bottom of a shoe 'having an upper,` insoleand welt extending entirely. around the shoebottom, interposing an orthopedic cushion heel lift between the` heel and said offset'portion of the outsole,

and stitching the marginal portion of the sole,l cushion heel lift, and welt together.

Intestimony whereof, I have signed my name' to thisspeciication, in the presence of two subscribing witnesses.
